GNIS

I have recently obtained the Geographic Names database (GNIS) on cdrom. I am
running GRASS on a SUN workstation under Solaris 2.3. Are there any programs
available which will incorporate this database into GRASS from the cdrom. If
not, what is the format of these files on the cdrom.

Thanks in advance

There are no grass tools per se that support importing GNIS, but we wrote a
series of awk scripts to do the conversion to site list format. You can
contact me directly if you would like copies of those scripts.

The tape format for GNIS is as follows (I assume that the cdrom is the same,
but I don't know that for sure):

raw GNIS file: 240-char fixed-length ASCII records with fixed-length fields

      cols wid id description
      ------- --- ------- -----------
   1 1-100 100 name official geographic name
   2 101-109 9 desig feature type or class
   3 110-144 35 county county containing (most of) feature
   4 145-155 11 loc (1 or 2) FIPS 5-digit state/county code(s)
   5 156-170 15 latlong primary geographic coordinates: ddmmssNdddmmssW
   6 171-185 15 heads source geographic coordinates (if linear feature)
   7 186-190 5 elev elevation in feet
   8 191-240 50 mapname primary topo map on which feature is indicated
